IEC 63002:2025 pdf download,Interoperability specifications and communication method for external power supplies used with computing and consumer electronics devices.
IEC 63002:2025 establishes comprehensive guidelines for charging interoperability among power sources, including external power supplies (EPSs) and other sources, specifically designed for use with computing and consumer electronics devices that adhere to the IEC 62680-1-3 (USB Type-C® Cable and Connector Specification). This document outlines the normative requirements that an EPS must meet to ensure seamless interoperability, detailing the data exchanged between the power source and the device, as well as certain safety considerations related to the EPS, cable, and device.
While the primary focus of this document is on the EPS and its behavior at the USB Type-C connector interface, it is equally important to understand the capabilities and behaviors of cable assemblies and devices to guarantee end-to-end charging interoperability. It is worth noting that this document does not encompass all design aspects of an EPS, nor does it specify regulatory compliance requirements related to product safety, electromagnetic compatibility (EMC), or energy efficiency.
Additionally, the document offers recommendations regarding device behavior when paired with a power source that complies with its guidelines. It specifies the minimum hardware requirements for an EPS that implements IEC 62680-1-3. Furthermore, it details the data objects utilized by a charging system based on IEC 62680-1-2, which helps in identifying the characteristics, design, performance, and operational status of an external power supply. IEC 62680-1-2 is particularly focused on power delivery applications that can reach up to 240 W, catering to a wide range of computing and consumer electronics devices, including laptops, tablets, smartphones, compact desktops, monitors, and various multimedia devices.
This document builds upon established mechanical and electrical specifications, as well as communication protocols defined by IEC 62680-1-2 and IEC 62680-1-3. These specifications facilitate the establishment of optimal interoperability between untested combinations of EPSs and devices, ultimately enhancing consumer satisfaction.
To support the implementation of this document, it also provides information on the USB charging interoperability model, an overview of USB Type-C and USB Power Delivery specifications, and factors influencing charging performance. The third edition of this standard supersedes the second edition published in 2021 and represents a significant technical revision.
Key technical updates in this edition compared to the previous one include: a) An increase in the power range to 240 W; b) The introduction of AVS mode; c) Updates in Annex A addressing issues related to arbitrary combinations of AC adapters and devices; d) New safeguards for EPR mode described in Annex B; e) Revisions to Annex C and Annex D.
